Yesterday, Michael Sam was known principally as a fierce and ferocious 260-pound Missouri defensive end, the 2013 SEC Defensive Player of the Year and a potential high-round pick in May's NFL draft. From the draftnik's notebooks: He holds the point of attack. He has a good motor. He can play 4-3 or 3-4. True, Sam played unremarkably at the Senior Bowl last month, but he was stationed for the first time at outside linebacker. His maturity -- he's already 24 -- and work ethic reside on the extreme edge of the bell curve.
